Yoshimura RS-9 Race Exhaust System Honda Grom MSX125

The Yoshimura RS-9 Exhaust System is the result of working with top AMA Pro riders to achieve mass centralization, maximum performance, and optimize rider usability with a dual muffler setup. The vertical pipe divider on the Yoshimura RS-9 exhaust splits exhaust gases more evenly over the stock system, resulting in power gains in the mid to top end RPM range. The uniquely sculpted Carbon Fiber end-caps feature a Tunable Insert System, this allows for fine-tuning of decibel levels and power delivery based on personal preference.
